FOU R-WAY REVRSE-VALVE.

SPECIFICATION forming part of Letters Patent No. 5 88,458, dated August17, 1897.

To all whom it may 0077206770:

Be it known that I, FREDERIOK V. MATTON, a subject of the King of Swedenand Norway, and a resident of Oamden, Camden county, New Jersey, haveinvented certain Improvements in Fouray ReVerse-Valves, of which thefollowing is a specification.

The objects of my invention are to construct a simple and effective formof four-way reverse-valve which can be readily operated, will providepassages of large area for the flow of fluid, and will indicate in whichdirection the fluid is flowng through the same. These objects I attainin the manner hereinafter set forth, reference being had to theaccompanying drawings, in which- Figure 1 is a longitudinal sectionalViewof a four-way reverse-valve constructed in accordance with myinvention. Fig. 2 is a transverse section of part of the same. Fig. 3 isa top or plan View. Fig. 4 is a top or plan View of the valve-seat, andFigs. 5 and 6 are views illustrating in different positions the index orindicator which shows the direction of flow of fluid through the valve.

The casing 1 of the valve' has branches 2 V 3 at opposite sides andbranches 4-5 at opposite ends, the bottom of the casing being closed bya base-plate 6 and thetop of the casing by a cap-plate 7, and theinterior of the ValVe-casing is divided by means of horizontalpartitions 9 and 10, Vertical longitudinal partitions 11 and 12, and avertical transverse partition 13 into an upper chamber 14, a lowerchamber 15, intermediate chambers 16 and 17, and side chambers 19 and20, as clearly represented in Figs. 1 and 2 of the drawings. v

An opening` 21 is formed in the horizontal partition 9 on one side ofthe transverse partition 13 therein, and on the opposite side of saidpartition 13 the partition 9 has another opening 22 formed in it, and inlike manner openings 23. and 24 are formed in the horizontal partition10 on opposite sides of the* central partition 13, the opening 22 beingsomewhat largerin diameter than the open- 24 in order that it-mayreceive an annular valve-seat 25, which is Secured to the partition 9 inany 'available manner.

. Through suitable stuffing-boxes in the top or cap plate 7 of theValve-casing pass Valvestems 26 and 27, and at the cute-r end of each ofsaid valve-steme are nu ts 28 and 29, which bear upon the upper andlower sides of one of the forked arms of a lever 30, which is c'entrallyexpanded so as to form a box or cage 31, having bearings for thetrunnions 32 of a nut 33, to which is adapted a screw-'stem '34, mountedin a bearn g 35 on the top plate 7, so that it is free to turn, but canhave no Vertical movement, the upper end of the screw-stem 34 having anOperating wheel or handle '36, whereby it may be readily manipulated.

To the inner end of the valve-stem 26 is pivoted a valve 37, which playsin the upper chamber 14 of the valve-casing andis adapted by adowhward'movement to closethe opening 21 in the horizontal partition 9,said valve 37 having a depending stem 38, which passes through anopening in a guide-rib 39, crossing the opening 21, and is pivoted atits lower end to the upper end of the stem 40, which passes through anopening in a guide-rib 41, crossing the opening and carrying at itslower end a valve 42, which plays in the lower chamber 15 of thevalve-casing andis adapted to close the opening by an Upward movement.

The valve-stem 27 passes through an opening in a guide-rib 43, crossingthe annular valve-seat 25, and to the inner end of said valve-stem ispivoted a valve 44, which is adapted to play in the intermediate chamber17 of the Valve-casing and to close by an upward movement the opening inthe valveseat 25, and from this valve 44 depends a stem 45, to the lowerend of which is pivoted avalve 46, having a depending stem 47,whichpasses through an opening'in a guide-rib 48, crossing the opening 24 inthe lower partition 10, said valve 46 also playing in the intermediatechamber 17 of the valve-casing and being adapted to close the opening 24by a downward movement. r

t Secured to the screw-stem 34 is a spor-'pinion 50, which meshes with aspur-wheel 51, the latter turning on a short spindle carried by a plate,52,.and on the upperface of this plate are formed two pairs ofconverging arrows, as shown in Figs. 5 and 6, the pair of IOO arrows onone side of the axis of the wheel 51 curving to the right and the pairon the other side of the axis of said wheel curving to the left.

The wheel 51 has two wide spokes separated by two wide spaces which bearsuch relation to the arrows marked upon the upper face of the plate 52that when one arrow of each pair is exposed through the spaces in thewheel 51 the other arrow of each pair will be hidden from View by thespokes of the wheel.

When the valve is ad justed to the position shown in Figs. l, 2, and3-that is to say, when the ValVes 42 and 44 are closed and the valves 37and 46 are openfluid entering the Valve-ehest through the branch 5 willpass from the intermediate chamber 17 into the lower chamber 15, thencethrough the side chanher 20 to the branch 3, which may be connected to apipe leading to the purifier or other apparatus. On its return the fluidenters the chamber 16 through the branch 4, passes thence into the upperehamber 14 and out through the side branch 2, or with the parts in theposition shown the fiow may, if desired, be the direct reverse of this.

hen the position of the ValVes is changed-- that is to say, when thevalvcs 37 and 40 are closed and the valves 42 and 44 are openedfluidentering the branch 5 passes *from the intermediate chamber 17 into theupper chamber 14 and thence out through the branch 2, and returningthrough the branch 4 passes from the intermediate chamber 16 into thelower chamber 15, and thence through the side chamber 20 to the branch3, or the flow in this case also may be in precisely the reversedirection.

Owing to the pivotal connection of the Valves with each other and withthe operating ValVe-stems, the seating of one valve is not affected bythat of the other valve of the pair, and by reason of the leverconnection between the Operating screw-stem 34 and the valve-stems 26and 27 any defect which might otherwise arise from a Valve of one stemcoming in contact with its seat before a valve of the other sten isefectually obviated, while the external index or indicator shows clearlyto the operator the direction in which the fluid is traveling in theValvechest, it being understood that the number of teeth in the pinion50 is so proportioned in respect to the number of teeth in the spurwheel51 that when either pair of valves is seated the spur wheel occupies aposition which exposes the proper arrows to indicate the direction offlow effected bysnch adjustment of the Valves.

It will be evident that a reverse construction of indicator maybeadopted without departing-fron my inVention-that is to say, the arrowsmay be formed upon the spurwheel and the blanks may form part of and thespaces maybe formed in a shield-plate for said spur-wheel.

The use of the detachable valVe-seat 25 is rendered necessary bythe factthat the valvcs 44 and 46 must be passed through the open ing in thehorizontal partition 9 in order to assume their proper position in theintermediate chamber 17.

The use of the side chamber 19 is not essential, nor would the sidechanber 20 be required it' it were not for the advisability of locatingthe branches 2 and 3 in line with each other, since it is manifest thatsaid chamber 20 could he abandoned if the branch 3 communicated directlywith the lower chanber 15 of the chest.

Having thus described my invention, I claim and desire to secure byLetters Patentl.
